Trivia: The scenes of Billy and Christie gawking at the final battle between the two ninjas were filmed months after principal photography. Lucinda Dickey is wearing a wig because she had already cut her hair short for her role in Breakin'.

Christie: For your information Billy, I don't believe in demons, ghosts, spirits, or any of that kind of stuff.
Secord: Well neither do I, but when you black out we don't know what you believe in do we?

Black Ninja: You fool! You can not stop me! I am the ninja! No one, nothing can stop me.

Secord: You know? I am sick and tired about hearing how you don't like cops, cause I'm gonna tell you something Ms. Independence. I like being a cop. And if you don't want to go out with me just because I'm a cop, then the hell with you lady.
